'Application ledfpllarch 6, 1925. Serial No. 13,604.

This invention is a novel motion picture apparatus, and generally speaking theprinciples involved are applicable either to an4 exposing apparatus or camera, or on the other hand4 to a projecting apparatusor lantern. I j

One of the main objects of the present invention is to aiford amotion picture apparatus of such improved compactness,s simy plicity, convenience and'inexpensiveness as to render it available for amateurs and home use. Furthery objects are to aiford an appa- .jratus of improved eicienc'y, accuracy and durability; especially with a spiral series ot' images upon a rotary disk 'record,"and to improve the v,manner of actuatingthe disk record tol rotate and progressively shift.`

A specialobject is to provide automatic means to restore and reset a'rotaryl disk proe 20 jecti-ng apparatus' for restarting so that. the

"picture series will lbe re eated again and v vagain without'the needo attention.

A further object is to'provide for the auto-v4 matic pause of the disk at a selected point, so as to-afford Astill projection of an inscription, title, advertisement or other image,for substantial duration, without stoppage of -the`a paratus as a whole.

lAiurther object is to provide a practical mechanism for projection of opaque motion pictures by reflected li ht. Y'

vQther advantages o the present invention will be elucidated in the hereinafter .following description of one or more embodiments thereof or will be understood to those skilled in the subject. To the attainment of the recited objects and advantages the present 'invention consists in the novel motion icture apparatus and the novel features o combination, arrangement, operation, construction and detailherein -shown or described.v

In the accompanying drawings Fig. 1 may be considered a front elevation of a motion picture machine embodying the present inv vention, considering the front as the slde toward which the images `are' projected; the picture disk "or yrecord being omitted, and

Fig. 8k shows a modified embodiment', andI may be considered as either a plan view or an elevation of certain parts. j

Fig. 9 is a partial front view of certain parts shown in Fig. 8.

The machine is shown as having a base plate 10 which supports the several mechanisms and which itself may be shiftable angularly and otherwise, and tiltable, in order to direct the mechamsm properl towards the subject or curtain. Upstan ing from the base 10 is shown a main frame wall 11, giving support to much of the mechanism,

and at the right end, is a rigid bracket 12 extending upwardly to where it gives support to certain of the mechanism.y Spaced away -rom the main wall 11 is a rear wall or plate 13, shown partly broken away in Fig. 2, and held in rigid relation to the remainder of the frame by means of posts 14. extending between the main wall and the plate 13.

The record or image carrier 15 is shown as a large' circular disk, which may be transparent for the purpose of projection No through the record, although as in Figs. 8 and 9 it may be opaque. The image record 15 may be either a sensitive plate upon which images are to be exposed and developed, or a developed and printed record suitable for projection. In either case there will be a succession or series of image spaces 16, arranged substantially as partially shown in Fig. 2, the image 16 being the first of the series and the succeeding ones trending u@ peripherally around the disk and gradually inward in a spiral manner toward the cenfour motion feed device or finger as Will be described. The disk may have a central aperture at the point 18 in Fig. 3 and a second aperture at the point 19 spaced from the center for the purpose of insuring accurate positioning of the record in the machine. It is to be understood that the record maybe removed or inserted, and when inserted may be progressively operated to project the entire series of images to produce motion pictures,Y and that any record may be vreplaced with any other record at will.

When the recordl is introduced into the machine it may be engaged and supported substantially as follows. A metal supporting disk 21 is shown, secured upon a short rotary shaft 22 and having a positioning pin 23. The disk central aperture 18 engages over the shaft 22 and the aperture 19 engages over the positioning pin 23, thereby accurately determining the position of the record disk in the machine. When the record is thus applied to the supporting disk it may be held by a spring clamp device 25 of spider form, seen in Figs. 1, 3, and 4, the bent arms applying pressure to hold parts of the record firmly against the rotary support. The clamp device 25 may be manipulated by its knob or handle 26. One of the bent arms is formed with a notch 27 to engage a pin 23, thereby properly positioning the clamp. A spring catch 28 1s mounted in the knob 26 in a manner to engage a slot in 'the shaft 22, thus latching the clamp in place. To remove the image record 1t is only necessary to press the spring catch 28 and remove the spider clamp 25, upon which the record may be detached.

As already indicated the image record is to be not only rotatable to bring successive peripheral portions to the optical osition, but is to be shifted, or moved bodi y transversely of its axis in a lateral or horizontal manner so as to give the progressive advane necessary to correspond with the spiral arrangement of the images. For the purpose of lateral @movements the rotary shaft 22 which carries the holding disk 21 and record l5 ma be journalled in a block or carria e 30 w ich 1s fitted snugly in a horizonte, slot 31 formed in the frame Wall 11, the carriage havin# its flanges embracing the opposite sides of the Wall, giving stead1 montes ness, While permitting the carriage to slide horizontally for a distance equal substantially to the eifective radius of the picture disk.` The disk thereby is so mounted 'that it may be rotated, and also bodily shifted transversely of its axis of rotation, so as to bring all portions of its surface in line with the optical axis.

One preferred feature of this invention is that the horizontal or progressive shifting movement of the disk and carriage shall be effected, not directly from the drive mechanism, but from the rotation of the disk itself. This insures proper coordination in the rot-ary and sliding movements. There is shown a horizontal feed screw or Worm 34, having a pitch coresponding to the pitch of the convolutions of the image spiral and adapted to shift the carriage and the disk mounted thereon. This feed worm 34 passes lthrough and is journalled in the rear ilange 32 of the carriage 30. A member or arm 33, later to be referred to, engaged on the Worm outside the flange, effects axial movement of the Worm 34 in one direction, as fully described below. The Worm however may rotate in the lia-nge 32, and at its left or interior end is provided with a bevel gear 35 engaging a corresponding bevel gear on the disk shaft 22. By this arrangement one complete rotation of the disk and shaft 22 produces one complete rotation of the worm 34. The right or outer end of the Worin is arranged 'to slide and rotate freely Within a bearing block 36 secured at the upper end of the fixed frame standard 12, and the outer extremity of the Worm is shown provided "with a knurled head 37 to facilitate manipulation. Instead of engaging in the interior threads of a nut the feed worin 34 is shown as engaged by a single pin or follower 38, which is normally fixed 1n position, so that the rotation of the disk and Worm effects synchronic and correspond-ing horizontal' shifting thereof, the Worm shifting, or translating, axially, responsive to the drive power of gear 35, glving a resultant spiral, -and servingk to bring the entire series of image spaces successively to the optical d osition. TWhen the follower 38 is disengaged from the Worm, said Worm maybe' axially shifted by hand without rotation. y

Coming to the optical part of the apparatus, the frame Wall 11 is shown formed with a. circular hole 40 through which projection takes place. ln front of the wall opening 40 is the objective lens 42, which may be of usual type, having a focusing sleeve 43. A screw device 44 operates to adjust the lens vertically to adapt it to the position of the images on the record disk. These elements may be mounted bodil upon a swingingl arm 45 which is pivote at its lower end at 46 so as to swing forwardly and down in order to give access for in# serting and removing records. The upper end of the swinging post or arm 45 is enlarged into the form of a light shield 47, centrally carrying the objective lens. When these parts are in normal position as 'seen in Figs. 1 and 7 they are held latehed there by a spring latch device 48. Mounted at the rear end of the objective lens tube is shown a vconical extension or tube 49, the rear or interior end of which is formed with a square Window 5() corresponding in size and positionwith the successive images. This window is 'adjusted upwardly and downwardly together with the objec` tive lens bv the screw 44. In Fig. 7 the Vpicture disk is shown as contacting snugly against the window tube 49. It is desirable to have a resilient pressure-holding the disk forwardly against the window 50, and for this purpose a bent spring 52 is shown, having a cut away area or window 53, as seen separately in Fig. 6, the spring being secured to the frame Wall 11 by screws 54. The spring presser plate 52 is so formed that it may be pulled backward and thus slightly retracted from the picture disk, so as to relieve the pressure and permit free rotation of the disk without scraping contact and possible injury, when desired. For the purpose of so reti-acting 4the spring presser a headed pin 55 is shown passing through the frame wall 11 and adapted bot-h to slide and rotate. The

rear end of the pin 55 has a lateral arm or rocker 56, which may be moved by hand to retract the presser. This may -convenij ently be donc through a fixed sleeve cam 57 mounted -on the frame wall, its rear or cam surface being so formed that when the rock arm 56 is swung over to the left, toward the observer in Fig. 7 the arm and therefore the piu 55 are `cammed rearwardly, so that the head of the pin forces the presser away from the picture disk. Later will be explained how the rock arm 56 may be automatically actuated at certain times.

To the rear of the objective lens, picture disk, and the frame wall window 4() is shown a. condenser lens 60, and to the rear of this is a source of illumination, which may be an encased electric lamp 62. This may be rendered adjustable to the axisvof projection by having a downward stem 63 passing through a carriage 64.y The lamp rods 66. The lamp case 62 mayenclosea condensing lens cooperating with the other lenses, and no clama 1s made to any `novelty in the lens system herein indicated.

This completes the description of the optical kpart of the apparatus, with the excep tion of the shutter, to be described in connection with the driving and disk feeding mechanisms.

The driving and peripheral feed mechanism m'ay be as follows. A drive shaft 70 is indicated carrying a crank 71 so that muscular power, can be applied to the machine, all the movements taking their actuation from this source. Instead of a crank an electric drive may be used, a motor being geared down to give a rotary speed resulting in `16 exposures per second more or less. Thedrive shaft is shown as passing through an elongated bearing 72 at the rear side of theframe plate 13. At its inner extremity the shaft carries a spur gear. 73 and in front of that a bevel gear 74 adapted to drive the second shifter, or resetting shaft 100 hereafter to be described. The spur gear 73 is shown in mesh with a pinion 75 on a short" countershaft which also carries a gear 76 engaging in t-urn a pinion 77 on the llnain shaft 78, socalled because this shaft carries the shutter and thecontrolmeans for the picture disk feed. The described gearing will be seen to give multiplied motion so that a slow steady turn of the crank gives the necessary speed of rotation of the main or cam shaft 78, which makes one revolution for each advancing step of the picture disk.

lA shutter 80 is shown attached to the main shaft 78, the same consisting of three wings in balanced arrangement, one of the wings servinv to obstruct the light path during each eed movement of the picture disk, projection taking place through the spaces between the three wings. The shutter also has substantial thickness and weight so asto serve as a steadying fly wheel.

Referring to Fig. 7 andothers the main shaft 78 is seen to carry two cams 82 and 83, the cam 82 serving to vibrate upwardly and downwardly the feed carriage to be described, and the cam 83 serving to advance the feed member into contact with the picture record, and retract it. The feed member" being mounted on the vibrating carriage thus receives four motions namely up, forward to engage the record., downward to advance the record. and rearward to disengage the record. The cam 82 is in the: nature of an eccentric., but is shaped as indicated in Fig. 2 to give a quick feeding movement, with a pause. and a smooth return movement. The cam 83 is not fixed to the cam shaft but is axially movable and capable of sliding forwardly and rearwardly, guided and limited by a key slot and pin device, a spring 84 pressing the cam for-V wardly toits normal position, as shown in Fig. v7, the purpose of the spring being to permit yield of the cam, so that it can be displaced or forced backwardly, as will be explained, to prevent its moving the feed Cil member into operative feed engagement with the picture disk at certain times.

The four motion feed device may consist.

of a feed point or pin 86 adapted to enter and engage the successive feed a ertures 17 in the picture disk. The fee point is mounted at the upper end of a light resilient body or spring linger 87 which in turn is given reciprocal feed movement longitudinally of the linger and up and down by the carriage yet to be described. The lower end of the feed finger is pivoted at 88 upon an extension of the carriage for reciprocal movement transversely of the disk, and a spring 89 surrounds the pivot pin, operating always to press the feed finger rearwardly, in a direction away from engagement with the picture disk. The finger cam 83 being an open cam, pressing forwardly on the feed finger at certain times, the springv89 acts to hold the finger pressedrearwardly into engagement with the cam. The feed linger and feed point may be adjusted laterally soas exactly operatively to register with they feed apertures, for example by means of a slot 90 formed in the feed finger, engaged by a guide pin 91, mounted on a slide bar 92, seen at the left lpart of Fig. 1, the extremity of the bar being seen in Fig. 1"^, Where an adjusting "device, consisting of a thumb screw 93, is arranged to shift the.

bar minutely and thus adjust the feed device laterally to the feed perforations. Y

The feed linger is carried on .a vibrating carriage 85 moved upwardly and down-- wardly so as to reciprocate alongside the disk by the cam 82. The vertical side edges of the carriage are guided in vertical guides 96, and the rear side of the carriage is provided with flanges 97 respectively overlying and underlying the carriage vibrating cam 82. T he carriage and connected parts are shown arranged somewhat below the optical axis, as seen in Figs. l and 2, and as the feed {inge-r ope'ates at a point somewhatlower than the center of the picture disk the carriage and guides are arranged at a slight incline from the vertical, so that the feed finger movements will be tangent to the line of perforations. An important structural feature is the relative arrangement of the parts as described and shown, the carriage 85 being formed with an o ening or slot 98 through which the main s raft 78 extends, so that the two cams 82 and 83 can be arranged in close proximity to the carriage and feed linger, and yet driven from a point to the rear. l f

The mechanism so far described is suliicient and complete for hand operation. The turning of the crank puts the entire series of pictures through successive exposures. W'hen the end of the series is reached the feed ceases because there are nofurther perforations 17 to be engaged by the feed Lacasse worm operations can be repeated.

A quick return or resetting mechanism operated by the crank or drive shaft may be as follows. The .second shifter, or resetting worm shaft 100 is shown as axially stationary and having bearings in the frame parts 12 and 13. This is beneath and somewhat to the front of the main worm 34. It has a bevel gear 101 engaging the bevel' gear 74 on the drive shaft, and the worm shaft 100 could be employed as the drive shaft if desired'. The grooves of the return worm 100 are cut in the same manner as the main worm, but the follower instead of the 'worm shifts, giving therefore a rapid reverse feed motion, which may be transmitted as follows to the carriage 30 and the spiral playing record. A follower pin 103 is arranged to' engage the grooves of the worm 100, this follower being mounted on a rock arm 104, which is shown secured to a collar 105, hav- .ing a pin'or spline 106 engaging the longitudinal groove or slot 107 in a rock'shaft 108- The collar and roel: arm thereby may lslide along the grooved shaft, but are comvwhich is yoked at its upper end and straddles the worm 34 adjacent to the flange 32 of the carriage 30, so that the carriage, the plate 33, the collar and the rock arm 104 are compelled to travel longitudinally as a unit. The rock shaft 108 at its right hand or outer end has attached to it a second rock arm 109 which carries the follower 38 engaging the main worm 34. Incidentally the rock arm 109 has a late cam 110 at its top end, shown separat-ely in Fig. 5, for a purpose to be described.

By this arrangement the feed follower 38 and the return follower 103 are interconnected, through the rock shaft 108, so lthat one or the other, but not both of them, will be engaged with the respective worms, engagement with one-alternating with that of the other. Also it will 'be perceived that follower parts of the shifting mechanism control with which shifter the shifting is to be effected. By this arrangement when a .record has lbeen completely exposed the move the collar 105 the worm 34, and theV Vbelow its fulcrum sha elm-iig?.V 3o' .entrainant posit-i035, A de;

In order to insure theengagement of one or theother of the followers with their re-y spective worms av spring arrangement 113 may be employed, such 'as-be'st'illustrated in Fig. 3, this sprin beingA attached to the lever 109, and arrange to ull it toward a point 108, so that in either position the spring tends to throw the lever away from ja mid position.v Thusr in full lines the "spring is tending to engage folloWerBS With'the worm 34;` while in dotted llines it is pulling reversely to engage follower'103 withthe worm 100.

e The entire mechanism may be coordinated to cause successive re ated operations of the same picture disk w rolly automatically and -without any attention from thev operator.

- are engaged b v extremity of t e wormshaft 100. The size and'iunnber of teeth of the cam wheel are For this purpose the control may come from a' slow moving controller, or cam wheel 115, fulcrumed on a bracket 116 attached to ythe standard 12. -r The periphery of the cam wheel 115 is` formed with gear teeth 117 which a worm118formed at the such that the wheel would make exactly one complete rotation with each complete cycle of operations :One function of the control cam 115 isqtofshift from slow forward feed to quick returnQfeed of the picture disk, andl this is shown-as'herein erformed through a. cam or block 119,-on t e periphery of the wheel, arrangedfto strike a'pin 120 at the lower end of a lever arm 121 which is fulcrumed at 122 on a fixed bracket 123, and

has an upward extension 124 cooperating with the plate cam 110 on the follower arm 109v already referred to. As shown in Fig. 2 the cam block 119 has not yet reached engaging position, but when it does so it will press upon lthe pin 120, swinging the lever 121 against' the resistance of spring 125,

l`while the iipper lever arm 124 moves inwardly against cam 110, as seen in plan view in Fig. 5. The control cam in this wa causes the cammin forward of the lroc Varmv 109, and when 1t passes its mid position 'thefspring 113 will cause vthe arm to snap away, the rock shaft 108 operating to snap the other rock arm 104 tocarry the follower 103 into engagement with the return worm 100. When the cam block 119 has 'passed the pin 120 it releases it, to return to the normal position shown in Fig. 2.

yAt the end of the return movement the finger 112 operates as described to disenga e follower 103, and the spring 113 causes t e feed follower 38 to snap back into engagement with the feed worm, thus causing repetition of actions.

. An auxiliary connection serving to re Amove the pressure and friction on the picture disk during they rapid return movement may be as follows. The upper. end of the lever arm 124, controlled by the cam wheel 115, has a long link connection 127 to the rock arm 56 already referred to, connected with the pin 55, the head of which overlies the spring presser 52. In this way the pressure is removed from the disk until the control cam permits the parts to resume normal position )ust prior to the restarting ofthe record.

Another function of the control cam is to render the peripheral feed mechanism inoperative during certain predetermined periods, while the rest of the mechanism continues acting. This is preferably done by preventing the feed finger 86 from engaging operatively with the picture record, namely by forcing the feed finger cam 83 rearwardly so that it will not operate to move the finger into engagement with the record, the locus of the path of the feedfinger being thus altered. As already explained the cam is arranged to yield resiliently for this purpose. This effect may be secured through a forked lever 130- which straddles the cam shaft v7 8 and is arranged to press back upon the forward sidey of the hub of the cam 83. The forked lever is fulcrumed at 131 and has a downward extension 132 adapted to be thrown forwardly by a trip or cam 133. The cam 133 has a bevel face arranged to press forwardly the lever arm 132, and is fulcrumed at 134. The cam may be actuated through a long link 135, see extending across the machine, the far end supported by an arm 136, with a spring 137 pulling on the arm 136 and tending to hold the cam 133 inoperative. The'arm 136 has a cam pin 138 adapted to be contacted'and thrust by an elongated additional cam block 139 on the cam wheel 115. When the cam block strikes the pin 138 this throws the. trip 133 and represses the feed finger cam Figs. 2 and 7 v sult is that there will be, during the suspension, the still projection of the image in ront of the opticalwindow. This scheme is of value in order to hold a title or inscription in position for any given length of time before resuming the projection of pictures. It will be understood that the total periphery of the control cam, with the feed suspensions referred to, shall be such that the actual feed of the record will be such as is necessary to carry it through from the initial to the final image. As herein shown the cam block 139 is so arranged as to suspend the feed at the final image, and again, after resetting, at the initial image.

When the cam block 139 reaches the pin 138 it will throw the feed mechanism into inoperative condition, so that the final image will be projected as a still picture. At this time the feed block 119 has not yet contacted the pin 120. lVhen it does contact the pin so as to throw 1the lever 124 this will effect the snapping of the combined lever 109, 104, disengaging the follower 38 and engaging the return follower 103 with the fast turning worm 100. The disk will thereby be reset, as described, and the finger 112 will restore the followers to initial position. Thereupon the first image Will be projected upon the curtain as a still picture, the feed still being suspended. When the cam block 139, completely passes by the pin 138 the feed parts are restored to operative condition and normal motion f picture operation commences, and continues until the entire series of pictures has been eX- posed.

In Figs. 8 and 9 is shown a modificationwherein the images are carried on an unperforated opaque picture disk 15n which may be a photographic reproduction on aper from the image negative. This disk has central aperture 18 and positioning hole 19, as in the main embodiment, and when in position lies flatly against a perforated disk 15b which may be of aluminum, cardboard o1' other light material, the perforations 17 cooperating with the feed mechanism already described. A lamp 62 is arranged to illuminate intensely the image 16b which lies in the optical axls, and the objective 42") projects the image upon the eurtain. This embodiment is particularly adapted for home use, is more safe against confiagration, and enables a cheaper 'image disk to be provided; although the distance of projection will not be so great as with the main embodiment.

It will thus be seen that there has been described a motion picture apparatus, available in some features either for a camera or for projecting purposes, and in other features for projecting purposes, the same embodying the principles and attaining the objects hereinbefore recited. Since many messes matters of combination, arrangement, construction and design may be variously modified without departing from the principles of the invention it is not intended to limit the same to such matters except so far as set forth in the appended claims.
